'acitizen of the United States, residing at New York, county of Kings, and State of New York, have invented certain new and useful improvements in Assembling Mechanism, fully described and represented in the following specification and the accompany ing' drawings, forming a part of the same.

This invention relates to certain'irnprovements in means for assembling printed products;

In producing a certain class of printedi e na e e o n:

products, such, for instance, as Weekly papers or magazines consisting of a considerable number of plies, it'is usual to sever the plies by] a cutter Which has a slightly serrated edge, as sucha cutter operates more satisfactoril'ynt high speed than a cutter which does not have its edge so formed. The serrated cutters, however, produce a product having a more or less rough edgeso that the'product has, a somewhat unfinished appearance. In many cases, this unfinished appearance Is ob1ectionable, and

it'is', therefore, customary to trim the prod-- net. The objectionable appearance of such a product can, however, be overcome by unit-in with it an outer .or cover sheet or sheets having hat is ordinarily termed a clean cut edge, this outer or cover product being composed of-u sheet 01 sheets which are slightly longer than the sheets of the inner product, so that the cover product overlaps and hides the rough edgefi 0f the inner product, thus makingit unnecessary to trim the complete product.

ihe present invention has for one of its objects to produce a mechanism which will assemble 'With an inner product an outer product which is slightly longer than the inner product, the products being assembled 1 so that their transverse fold lines will be in register.

A further object of the invention is to produce a. mechanism which will assemble two products of different lengths with their transverse centers, on which theproduct is folded, in register, said mechanism including suitable devices for securing; the prod ucts together.

A further object of the invent-ion is to produce certainimproved details of construction which may be advantageously employed in earrrying the invention into cflect.

rety oi Webs into sheets, the companion cylinder being lllustrat'ed at 4. In the particular construct on illustrated, the assembling cylin w'iththe usual knife 6 cooperating there -device, is an excellent one for carrying the with these other objects not specifigfiyrefi ra ie n new theew m er sen- .slsts, m. certain QQnstructi ns, and in can wi pers A P eme e res bi stien as will be hereinafterfully described and trates, in diagrammatic side eleyution, en

View ofthe assembling cylinder lllustrated in Fig. 2. e to 10 are d ta l se e r e llu t t n h op ra ion of cer ai g ip rs Wh h e'yl emplo ed outlieassembhng cylinder, a t p ljiiloular machine vhich'has been selected to v t e n. 91 1* e s ea e as P s be e s s t kb seiner e f nd n ping rolls 2 ,igvh'e 'pperate to bring the- Webs together. v heets cut. im en e Webs will form the ini fillio'r plies of the product t e n ily iue uq y h me n t s i 1 sheets being assembled. with the outer sheet or sheets by an assembhng mechanism which ay be va i d wide y in sat sfa ti n In the part1cular ,machme shown, the asse1nb'l' ng mechan sm, includes. e cylinder 3 n hichmay, as, shown, form one of a pair ofcuttifig cylinders for severing the webs der is rovided with three cutting blocks or we "s 5, and the cylinder 4 is provided with.

i The form of cutting mechanism Which'l'ias' just been described in which the assembling cyllnder carrles one member of the cutting invention into effect, but it is to be understood that the invention is not restricted to cutting mechanism in which the assembling cylinder when employed carries one ofthe cutting members. It isof course ap- I631: parent that the sheets termed by the cutting, mechanism referred towvillbe off eqnel predetermined length.

The assembling cylinder; vhen" i e of assembling mechanism is employed, 1116 shouldbe provided with devices for taking the sheets formed by the cutting devices. While these devices may be varied, in the particular construction illustrated, the sheets are taken by pairs of side grippers 7 pivoted in the ends of the cylinder, the projecting tails 8 of the grippers being provided with cam rolls 9 and arranged to contact as the cylinder rotates with Operating cams 10 secured to the frame of the machine, the construction being a usual one. The side grippers referred to take the leading ends of the webs and carry the webs forward, the cutting devices operating in the usual manner to sever the sheets from the webs. V

Machines embodyin the invention will include means for delivering to theassembling cylinder an outer sheet or sheets which will be slightly longer than the interior sheets, and one of these sheets may, if desired, form a cover. The difference in length will be slight, usually about a quarter of an inch, so that the edges of the exterior sheet or sheets will extend about one-sixteenth of an inch on each side beyond the edgesofthe interior sheets, thus hiding any roughness of cut on the interior sheets and giving the entire product, after the outer sheet or sheets have been applied, the appearance of a product which has been trimmed. The means for presenting to the assembling mechanism this outer sheet or sheets may be considerably varied. In the machine shown, the outer sheet or sheets, indicated at S, are assumed to be alternately forwarded from two sources, the sheets from one source being initially forwarded by a 1 set of feeding rolls 11, through a tape pathway 12 of ordinary form, to a sheet rest 13. Sheets from the other source are forwarded by a pair of feeding rolls 1%, through an ordinary tape pathway 15, to a sheet rest 16. The sheet rests 13 and 16 have timing steps 17 cooperating therewith, these timing stops being alternately operated through mechanism of the usual type indicated in dotted lines in Fig. l and not necessary to specificallydescribe, as it is well understood in the art. The sheets from the rest 13 are forwarded by a tape pathway 18 to a sheet support 19, and the sheets from the sheet rest 16 are forwarded by an ordinary tape pathway 20 to the sheet support 19, both sets of sheets passing between forwarding rollers 21. The inner edge of the support 19 is so located with respect to the assembling cylinder 3 as to deliver the sheets passing thereover to the sheets on the cylinder which have been cut from the webs as before referred to. The forwarding devices for the sheet which pass over the support 19 are,

,however, so timed as to cause these sheets to of the edges of the web sheets. It will be understood that'the sheets passing over the support 19 are, as has been indicated, slightly longer than the web sheets, andalthough their leading edges when they reach the cylinder 3 are slightly in advance of the web sheets on the cylinder, the transverse centers of the two sets of sheets will be in register.

The assembling mechanism will be provided with means for taking the exterior sheets. \Vhile the construction of these taking devices may be varied, in the construction illustrated, they comprise a set of edge grippers, these grippers including gripper so fingers 22 which operate upon the edges of the exterior sheets. While these edge grippers, when employed, may be variously mounted and operated, in the best construction they will be arranged so as to move from an inoperative position below and at one side of the cutting member to a position over it. In the particular construction illustrated, each set of fingers is carried on a shaft 23 mounted in the cylinder the ends of the cylinder being slotted, as at 24, to permit the shafts to move. Each of the shafts 23 is carried in arms 25 pivoted on a shaft 26 also mounted in the cylinder, these shafts 26 having operating arms 27 extending therefrom provided with rolls 28. The shafts 23 have operating arms 29 extending therefrom, these arms being provided with rolls 30. The rolls 28 are arranged to contact with cams 31 carried on the frame in 1 which the cylinder is mounted, and the rolls 30 are arranged to contact with cams 32 also carried on the frame. The cams 31 and 32, through the connections indicated, give the grippers a compound movement which 105 causes them to be carried from an inoperative position against a rest 33 below and at one side of the cutting member 5 to an operative position over said member.

The sheet S, in the particular machine 1 shown, are advanced by a roll 34 which cooperates with the roll 3 before referred to, this roll having a cut out portion 35 to per mit the operation of the edge grippers before referred to. The operation of these 5 grippers will be well understood from the detail views 4 to 10 inclusive. In the first of these views, the edge grippers 7 have taken the leading ends of the webs and are carrying them forward and the sheets S-are 25 -Wlll be in register. When the sheets have sive positions of the parts. In Fig. 7, the

grippers 22 are shown as having nearly com- '*pleted their movement toward the cylinder 34, the leading edge of the sheet S having ibeen'bent back and resting against the edges of the tails of the preceding sheets. In

. Fig. 8-, the grippers 22 are shown "as having entirely completed their movement toward the cylinder 34, the leading edge of the sheet Shas been cleared'from the tails-of the pre-.

cedin sheet, and have snapped backcnto .the cy inder 3, and the grippers 22 are ready to .begin'ftheir closing movement, the

051- tion "of the. parts when the grippers completed their .movement and taken the ed e of the sheet S beingshown in Fig. 10.- Wfien'the grippers 22have closed upon the l f leading edge'of the sheet S, the carrier .3

moves onward, advancing the sheets which have been taken by the two sets of grip ers. As has been stated, the leading edge 0 the f sheets are so positioned and the sheets S are so controlled in-their movement that when superposed upon the web sheets the transverse center lines of the twosets of sheets been thus assembled they should be secured together. ,The securing may be efiected in variousways, as, for instance, simply by folding the sheets,.but in machines embodyin the invention in its best form,'means 'wil be provided for positively unitin the sheets on their transverse center ines. When the securing means includes'means for uniting the sheets, these means may 'be of various descriptions. As shown, the cylin-- der 34 is provided with a staple forming and inserting plunger 36, this plunger cooperat- 'ing with afstaple former 37 and a clenching w stapling mechanism mdlcated 1n the drawmember38 on the cylinder 3. The-form ot' in s is well understood in the art and a speoi edescription of it is unnecessary.

When the securing means includes a folding mechanism any suitable type of folder may be employed; In the particular machine illustrated, the cylinder 3 is provided with three tucking blades, indicated at 39, these blades operating to insert the sheets at their fold lines between nipping jaws 4-0 of a usual type mounted on a cylinder 41, this cylinder operating, as usual in such'constructions, to deliver the folded a conveyer 4E2. r
